Introduction:The use of protein supplements, especially whey protein, has become quite common among bodybuilders due to its effectiveness in promoting hypertrophy and muscle recovery. Aim:To investigate how whey protein is being used by bodybuilders in gyms in Goiânia. Methodology: This cross-sectional study with a quantitative approach investigated the use of whey protein by 86 bodybuilders from gyms in Goiânia, aged between 18 and 59. Results: Data collected by questionnaire indicated that 72.1% used the supplement,most of them under the guidance of nutritionists (40%), but also with recommendations from physical education professionals (22%). Concentrated whey protein was the most consumed type due to its cost-effectiveness and effectiveness for hypertrophy and muscle recovery. Most users reported benefits such as improved performance during workouts (62.5%), although 15.3% did not maintain a consumption routine. Conclusion:The study reinforces the importance of professional guidance in the use of supplements and points to the need to delimit competencies between nutritionists and physical education professionals, while also highlighting socioeconomic influences on whey protein consumption. Future longitudinal research into the effects of supplementation in different populations and sportsdisciplines is suggested.
